This article concerns how to evaluate the integrity of managers, with an emphasis on identifying those with low integrity. After defining our terms, we review leadership research showing that subordinate perceptions of their manager's integrity determine how much they trust their manager which, in turn, influences their attitudes and performance. Next we evaluate a common method for assessing the integrity of managers. This method defines integrity as a leadership competency and measures it using coworker ratings of observed ethical behavior. We found that these behavioral ratings suggested only a negligible proportion of managers may have integrity issues and did not distinguish high- from low-performing managers. We then propose an alternative method based on subordinate expectations about the likelihood that their boss would behave unethically. This method suggested that a much larger proportion of managers may have integrity issues and did distinguish high- from low-performing managers. Based on these findings, we offer recommendations for assessing integrity in practice and urge the leadership field to seriously consider the prevalence and impact of managerial misconduct.

To embed goal theories more deeply in the domain of top-level leadership behavior and to provide a vehicle to facilitate future research, the authors developed a taxonomy of managerial goals. Interviews with 75 company leaders--founders and presidents--from 3 countries generated 2,182 articulated goals. Content analysis supported 2 taxonomic dimensions: goal content and hierarchical level. The goal content dimension specified 10 categories of substantive goal targets, and the second dimension captured the hierarchical structure of the top leaders' goal sets, with lower-level goals being instrumental toward achieving superordinate goals. The hierarchy comprised 5 goal levels: ultimate, enterprise, strategic, project, and process. Chi-square analyses revealed relationships between goal content and hierarchical level as well as differences between the national subsamples.

Can peer ratings identify managers who later are promoted rapidly in a large corporation? A representative sample of 56 graduates was selected from 4-week middle manager training classes where a lengthy 13 item peer rating was administered. When the mean peer ratings of 21 managers who received 2 or more promotions after graduation were compared with the mean peer ratings of 19 managers who received no promotions, differences were significant at the .01 level for all but 3 of the rating items. The results suggest that a large body of predictive data for industry exists in the judgments contemporary managers are able to make about each other.

What effect does the use of categories by various groups have on communication? What can be gained by analyzing categories of thought about jobs and people in industry? "Triads of jobs and people were presented to 105 Ss. The Ss were managers, clerks, and workers in a small New York State industrial concern. The Ss were asked 'Which one of these three jobs (people) is more different from the other two?' and 'Why?' The characteristics that differentiated one member of the triad from the other members were listed. Certain differences in the lists obtained from the various groups were observed. An attempt was made to assess the significance of these differences for inter-group communications in industry." (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

In the second part of this paper the problem of finding an exact model for a q-dimensional infinite time series is considered. First a mathematical vocabulary for discussing exact modelling is developed. It is then shown how the results of Part I guarantee the existence of a most powerful (AR) model for an observed time series. Two algorithms for obtaining such an (AR) model are subsequently derived. One of these algorithms gives a shortest lag input/output model. The problem of obtaining a minimal state space realization of the observed time series is also considered. In order to do that, realization theory based on the truncated behaviour is developed. As an extensive example, the classical situation with impulse response measurements is discussed. 相似文献
